Linlai E 6sn7 tubes

Many thanks @decooney . There's been so much written about the CV181, but it's not a drop-in replacement in some circuits. 

I'm looking for neutrality in a 6SN7 (similar to Sylvania). I'm awaiting delivery of a pair of Linlai E-6SN7's and if there are positive user reviews, I would give the Psvanes a try.

Regarding the AN Psvane, it's possible that Audio Note's valves meet tighter tolerances than the standard run. Similar to military tubes during wartime.

@lowrider57 oh, yes...that’s right... I do remember my local dealer mentioning that fact about the tubes that go to Peter at AN are more tightly matched.I’m sure he pays extra for it too. I had forgotten about that fact as I myself have resorted to seeking closer matched triode pairs in the premium boxes with test papers keeping my fingers crossed they might be a few % better and might last a tad bit longer now that I’m tube rolling less any more. These newer gen tubes are "good enough" for me and sounding nice. .

@decooney , you may have already mentioned this, but which premium tubes have you been using?

I have reserves of NOS and am starting my new tube experience with Linlai. 

@lowrider57 only the last two pairs of small signal 12ax7 and driver tubes and this last quad of cv181s / 6SN7s were true premium boxed sets.  The former Full Music 6SN7s were supposed to be premium match quads, two sets. Time will tell.  

I have read on the Supratek owner’s thread that Mick is shipping his preamps with these tubes. I think that says something positive about them.

I've sent him an email to confirm this and requested his opinion on these tubes.
